Cosmetic composition comprising porous particles incorporating optically active substances

摘要

An object of the invention is to offer an optical additive capable of adequately activating the effects of incorporated optically active substances, providing the base with such optical effects, having a suitable sensation and level of safety, and having exceptional cosmetic properties. A cosmetic composition comprising in a physiologically acceptable medium (a) silicium based porous particles having an aspect ratio of at least 2 and (b) an optically active substance incorporated into said porous particles is offered. The incorporated optically active substances are selected from among UV screening substances, fluorescent substances and photochromic substances.
